IMPROVEMENT IN FILTERS AND COOLERS.

Specification forming part of Letters Patent No. 40,329, dated October 20, 1863.

To all whom it may concern.-

Be it known that I, G. B. DAVIS, of Ohicago, in the county of (look and State of Illinois, have invented a new and Improved Water Filter and Cooler; and I do hereby declare that the following is a full, clear, and

exact description of the same, reference being had to the accompanying drawing, making a partofthis specification, said drawing being a vertical central section of my invention.

This invention consists in a novel and improved combination of a water filter and cooler, the parts pertaining thereto being ar ranged in such a manner that the water will be filtered in a thorough manner and allowed to pass into the cooler without the liability of coming in contact with the ice in the icechamber, the diii'erent chambers at the same time being rendered very accessible for the purpose of cleansing, 8m, when necessary.

To enable those skilled in the art to fully understand and construct my intention, I will proceed to describe it.

A represents the lower part of the device, which contains the ice-chamber B and coldwater chamber 0. This part A has double walls, the space between them being filled with charcoal or other suitable non-conducting substance, to. It is also provided with a hollow base filled with the same substance, at, and a piece of wood, b. The ice-chamber B is of circular form, inclosing the cold-water chamber 0, the upper part of which is provided with an opening, 0.

D is a faucet, the tube cl of which extends horizontally through the lower part of the icechamber to the cold-water chamber G, and e is a tube which admits of the escape of water from the ice chamber.

E represents the upper part of the device, which may be formed of a single wall, but provided with a 1id,f, made hollow'and filled with a non-conducting substance, 9. The part E fits within the upper part of A, and rests upon the top of the inner wall thereof, the outer wall extending upward sufficiently to form a flange, h, to keep E in proper position. The lower part of E is provided with a tube, '6, for the purpose of drawing the sediment from E, when necessary, and within E there is placed a perforated chamber, f, filled with any suitable filtering medium, j. At the center of the bottom of -the chamber F there is secured a perforated .conical projection, 7c, un-

derneath which a conical cork, G, is secured. This cork has a tube, 1, fitted in its center, which is in line with the projection 70, and when the part E is fitted on A the cork G is fitted snugly in the opening 0 in the top of the cold-water chamber U, and closes said opening perfectly tight, so that no water can escape or leak into the ice-chamber B. This cork stopper is an essential feature of the invention, as it admits of the part E being fitted on and removed from A with the greatest facility and without danger, as before stated, of any water passing into the ice-chamber. By keeping the ice thus free from moisture it is prevented from melting rapidly in the icechamber B. The ice-water-that is to say, that produced by the melting of the iceescapes through the tube 0.

The part E of the device is filled with water, which passes by gravity through the filterchamber F and perforated conical projection it into the tube-l of the cock G, and down through said tube l into the cold-water chamber 0, where it is cooled by the ice chamber B and drawn as wanted through the faucet D. The perforated conical projection is admits of a free passage of the filtered water into the tube 1, as a large perforated area is obtained for the passage of the water into the tube 1. This vis an essential feature, as the filtering medium obstructs the passage of the water considerably, and if a large area is not thus obtained the flow of the water would be too sluggish.

The apparatus, it will be seen, is extremely simple, may be constructed at a reasonable cost, and the different chambers being rendered very accessible they may be kept in a clean state without any trouble or difficulty whatever.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

The tilteringchamber E, provided with the stopper G, of cork or other suitable substance, in combination with the ice-chamber B and cold-water chamber 0, the latter being provided with an opening, 0, in its top to receive the stopper G, and all arranged as and for the purpose specified.

G. B. DAVIS.
